Jill takes in 0.0140 mol of air in a single breath. The air is taken in at 20.0°C and exhaled at 35.0°C. Her respiration rate is (1.30x10^1) breaths per minute. At what average rate does heat leave her body due to the temperature increase of the air? Provide your answer to three significant figures.
